The patients were predominantly male, with a M/F ratio of 4:1. Cardiovascular risk factors were mainly myocardial infarction (MI) (60%), hypertension (50%), obesity (40%) and diabetes (30%), with at least two risk factors per patient. Angina was the main symptom (80%). The average time from presentation to surgery was 8 months. The mean Euroscore 2 was 2.92 ± 1.65 [1.33 - 6.60]. Coronary angiography revealed an average of 2 lesions per patient, with 3-vessel involvement in 70% of cases: the Interventricular artery (IVA) (100%), the right coronary artery (90%) and the circumflex artery (70%). On echocardiography, the mean Left ventricular ejection fraction (LVEF) was 59% [33% - 76%]. All patients underwent median sternotomy with bypass grafting. The average duration of the cardiopulmonary bypass was 150 min [46 - 275 min];that of aortic clamping, 120 min [43 - 232 min]. The grafts used were internal thoracic artery (ITA) in 100% of cases (80% on the left and 20% on the right), and the great saphenous vein (GSV) in 60% of cases (50% on the left and 10 on the right). Double bypass was performed in 60% of cases, single bypass in 30% and triple bypass in 10%. The bypasses were performed on the IVA (100%), the middle lateral of the circumflex (30%) and the bisector (20%). The average time to extubation was 11 hours and the length of stay in the intensive care unit was 7 days [03 - 17 days]. One patient had a reoperation on Day 0 post-op. The average hospital stay was 13 days [06 - 27 days]. Complications occurred in nine of the patients (90%), with a predominance of infectious and neurological complications. Overall operative mortality was 3%, all in intensive care.展开更多

Low preoperative serum albumin is linked to poor outcomes, including acute kidney injury (AKI), after off-pump coronary artery bypass (OPCAB) surgery. This study aimed to assess the relationship between preoperative serum albumin levels and early postoperative renal injury. Methods: This prospective comparative cross-sectional study was conducted from August 2019 to February 2021 at the National Heart Foundation Hospital & Research Institute, Bangladesh. It included 160 adult patients with normal preoperative renal function undergoing OPCAB. Patients were divided into two groups: Group A (serum albumin ≥ 4.0 gm/dl) and Group B (serum albumin Results: Preoperative serum albumin was significantly different between groups (Group A: 4.21 ± 0.05 gm/dl, Group B: 3.69 ± 0.04 gm/dl, p = 0.028). Group B had a higher incidence of hypertension (71.25% vs. 51.25%, p st and 3rd postoperative days were higher in Group B (p th day. Postoperative AKI occurred in 18.75% of Group A and 36.25% of Group B. Multivariate regression indicated that low preoperative serum albumin is an independent risk factor for postoperative AKI (p = 0.012, OR = 1.815, CI: 0.675 - 1.162). Conclusion: Preoperative serum albumin level is a valuable predictor of postoperative renal function. Ensuring high normal serum albumin levels before surgery can help minimize the risk of postoperative AKI.展开更多

Coronary artery bypass grafting (CABG) has been increasingly used since the 1960s. Coronary heart disease is a leading cause of death worldwide, including Sudan. Self-efficacy and functional capacity is a critical factor for quality of life in patients who has undergone CABG as well as for their caregivers from their families. Aim of the Study: To explore the effects of an educational program on self-efficacy and functional capacity of patients after CABG. 1) There will be no significant difference between the intervention group and control group concerning knowledge regarding Self-efficacy and functional capacity post CABG surgery. 2) The application of our educational program for the patients will enhance the patients with CABG surgery and improve knowledge about Self-efficacy and functional capacity post CABG surgery. 3) There are some socio demographic factors that affect the response to the educational program. Methods: This was a quasi-experimental, interventional and hospital-based study, including pre-test, a post-test and follow-up test, with a control group, conducted during the period from September 2014 to June 2019. Patients were recruited consecutively to the cases and control group using convenience sampling. The sample consisted of 76 patients;41 as cases and 35 as control group. The sample included those who had undergone CABG in Khartoum State. Relevant data were collected using a checklist to monitor the effect of a health education program on self-efficacy and functional capacity of the patients. Result: The results showed marked improvement in patients’ self-efficacy and functional capacity between pretest and posttest for the study group;p-value = (0.001) in the health status of cases in comparison to the control group. The indices were observed to be higher for patients who received a nursing educational program throughout the study period;p-value = (0.002).展开更多

Whether this advantage of CABG over PCI is confined to diabetics who require insulin is unknown. We review the published literature comparing CABG with PCI in diabetics including 8 cohorts and 4,786 patients. There was a lower rate for all-cause mortality （Relative risk （RR）： 0.78, 95% confidence interval （CI）： 0.62-0.99）, and for major adverse cardiac and cerebrovascular events （MACCE, RR： 0.59, 95% CI： 0.47-0.75） for CABG compared to PCI. Composite outcome of mortality, myocardial infarction and stoke was similar between CABG and PCI （RR： 0.87, 95% CI： 0.54-1.42）. Visual inspection of the forest plots showed that in most analyses, the point estimates of the RR are similar between the insulin requiring group and non-insulin requiring group. On meta-regression, there was no interaction between status of insulin requirement and revascularization strategies （P 〉 0.05 for all）. The pre- sented data on the still unpublished analysis of the FREEDOM trial showed similar results. Thus, in the current era, CABG is superior to PCI with lower mortality and MACCE rates, but the state of insulin requirement had no effect on the outcomes from the two revascularization strategies.展开更多

Previous studies have reported a consequence of an increased risk of mortality while waiting for CABG. Identification of risk factors for mortality is important in patients waiting for CABG. Objectives: To assess mortality rates and identify risk factors for mortality of patients waiting for CABG. Methods: This retrospective cohort study was done on patients waiting for elective CABG in dr. Kariadi General Hospital from January 2018 to December 2020. Identification of risk factors associated with mortality was done on patients who were waiting for CABG using logistic regression methods. Results: There were 162 patients fulfilling the criteria, with a mean waiting time for surgery of 9.8 months. While waiting for CABG surgery, 32 (19.7%) patients died of any cause. Independent risk factors for death while waiting for CABG included left ventricular ejection fraction ≤ 45% (OR 4.75;95% CI 1.76 - 12.78;p = 0.002), left main disease (OR 4.12;95% CI 1.50 - 11.27;p = 0.006), serum creatinine ≥ 1.5 mg/dl (OR 3.71;95% CI 1.41 - 9.74;p = 0.008), and a number of coronary artery disease risk factors ≥ 3 (OR 3.34;95% CI 1.24 - 8.99;p = 0.017). Conclusions: Long waiting time for CABG is associated with a high mortality rate which is influenced by left ventricular ejection fraction ≤ 45%, left main disease, serum creatinine ≥ 1.5 mg/dl, and a number of coronary arteries disease risk factors ≥ 3.展开更多

Material and Methods: One thousand and ninety four patients who underwent coronary artery bypass surgery between January 2009 and December 2011 inour clinic were included into this study. Three hundred and thirteen female patients (group 1) were compared to 781 male patients (group 2). Results: The mean age of group 1 was 61.4 ± 9.6, and the mean age of group 2 was 58.1 ± 9.6 (p < 0.001). The ratio of diabetes mellitus and hypertension in group 1 was higher than that of group 2 (p < 0.001). There were no significant difference between two groups when compared regarding the need for inotropics after weaning from cardiopulmonary bypass, cross clamp and total cardiopulmonary bypass periods (p > 0.05). It was found that the amount of drainage was higher in group 1 than group 2 (p < 0.001). There was no significant difference between two groups when compared in terms of mortality, re-operation (because of bleeding), postoperative atrial fibrillation, need for intraaortic balloon pump, usage of levosimendan, cerebrovascular accident, chronic renal failure, discharging intervals and period in intensive care unit. It was found that sternal wound infection was higher in group 1 than group 2 (p < 0.05). Conclusion: We consider that female gender does not put an additional risk to increase mortality and morbidity in coronary artery bypass surgery.展开更多

Methods Between October 2002 to April 2003, twenty five cases underwent beating heart coronary artery revascularization without endotracheal general anesthesia, using high thoracic epidural anesthesia and analgesia. All the patients underwent epidural catheterization on the evening before the surgery. Resuits The patients in all received 71 grafts (single n = 11, double n = 5, triple n = 6, quadruple n = 3). Six patients underwent repeat coronary artery bypass. Except one was converted to general anesthesia and cardiopulmonary bypass, the other patients underwent off-pump coronary artery bypass graft surgery, 2 patients underwent grafting via left thoracotomy (MIDCAB) and the rest through mid sternotomy. There was no mortality. Mean length of stay in the intensive care unit was 16 .2 ( 4.2 hours and hospital was 3.0(1.2 days. Conclusions Our experience confirms the feasibility of performing multiple coronary artery bypasses in conscious patients without endotracheal general anesthesia展开更多

In the ...The association between atrial fibrillation（AF） after coronary artery bypass grafting（CABG） and the surgical techniques selected has been extensively reported. However, no consistent results were obtained. In the present study, a meta-analysis was conducted by searching the electronic databases Pub Med, Embase, Web of Science, and Cochrane to identify the association of post-CABG AF with on-pump（conventional CABG, c CABG） or off-pump CABG（OPCABG）. Outcomes from randomized clinical trials（RCTs） and propensity score matching（PSM） trials were pooled by using the fixed-effect or the random-effect modeling method, and verified by the quality-effect modeling method. There were 35 studies with 36 independent reports that met the inclusion criteria and were eventually included in our meta-analysis. The total odds ratio（OR） of the incidence of post-CABG AF between OPCABG and c CABG was 0.80（95% CI 0.71–0.91）. The 25 randomized clinical trials（RCTs） had an OR of 0.69（95% CI 0.56–0.86）, while the OR of the 11 PSM trials was 0.88（95% CI 0.77–1.00）. Twenty-six studies involving the patients at a mean age no more than 65 years showed an OR of 0.76（95% CI 0.64–0.90）, whereas 10 studies with patients greater than 65 years old showed an OR of 0.90（95% CI 0.78–1.05）. The results of this meta-analysis suggest that OPCAB surgery may reduce the incidence of post-CABG AF when compared to c CABG and that younger patients may benefit more from OPCAB and have a lower incidence of post-CABG AF.展开更多

Pre-operative use of intra-aortic balloon pump has been shown to prevent this complication in high risk patients. The role of balloon pump in high risk patients has been questioned by our group. We modified the role of balloon pump in our patients, thus avoiding the conversion to cardiopulmonary bypass. Methods: 4063 off-pump coronary bypass surgeries were performed by a single surgeon in our center, over thirteen years. 130 intra-aortic balloons used between July 2002 and December 2015 were removed from the the-ater, once the distal anastomosis was performed. We studied this group of patients for—time and need for insertion, duration of balloon used, local insertion problems and survival. Results: Initially, we inserted intra-aortic balloons in high risk patients. We observed that, patients with low ejection fraction and patients with critical left main coronary artery disease were not the ones who actually needed balloon pump support. It was the patients who had ongoing ischemia, with preserved left ventricular function, and ST depression intra-operatively, who needed balloon pump support to perform complete anatomical revascularization. Conclusions: Intra-aortic balloon pump has helped us to position the heart without hemodynamic instability, thereby avoiding conversion to cardio-pulmonary bypass. This enabled us to perform off-pump surgery in virtually all areas of the heart, thus maintaining perfect hemodynamics.展开更多

To avoid the deleterious effects of cardiopulmonary bypass, off pump coronary artery bypass grafting is becoming increasingly popular world wide. We reviewed our experience of complete coronary artery revascularization on the beating heart without CPB. Methods From Aug 1998 to Aug 2000, 860 off pump revascularizations (99%since January 1999) were performed at Manipal Hospital Heart Foundation. The patients consist of males 757(88%), females 103(12%). Averaged age 64.2±15 years. All surgeries were performed through a median sternotomy. Exposure techniques are tailored to individual vessels and cardiac regions. Local immobilization is performed with octopus. Vascular control is achieved with occluders and shunts. Results Among 860 off pump CABG patients. Single graft 72 (8.3%), two grafts 208 (24.2%), three grafts 469 (54.5%), four grafts 101 (11.8%), five graft 10 (1.2%). The average number of grafts per patient was 2.72±0.32. Operative mortality was 0.69%(6 patients). Anesthetic time 3.9±1.2hours, extubation time 6±2.5 hours, Blood requirement 360±90 ml, Preoperative LVEF 60.2±8.5%, Post LVEF 64.1±14%Low cardiac output 48 patients (5.6%), IABP requirement: 25 patients(2.9%), 25 patients converted to CPB during OP CAB(2.9%)and 20 of them were done with on pump beating heart. 25 patients showed myocardial ischemic and 16 patients showed perioperative myocardial infarction. ICU stay 1.1±0.8 days, hospital stay 6.2±1.1 days. Conclusion Off-pump coronary artery bypass in complete revascularization is a safe, effective technique and suitable.展开更多

One hundred patients with coronary artery diseases underwent elective CABG. In the group Ⅰ(n= 50), the left ITA was dissected using the skeletonization technique. In the group Ⅱ(n=50), the ITA was harvested as a pedicled graft. Free flow of the ITA was recorded before and 15 min after in- traluminal application of diluted papaverine. Mean arterial pressure was maintained at 9. 31 kPa (70 mmHg). The results showed that before the application of papaverine, free flow of skeletonized and pedicled ITA grafts was identical between the two groups. After treatment with papaverine, the maximum free flow was significantly higher in the skeletonized ITA's in the group Ⅰ(199. 3±69. 6 ml/min) than in the group Ⅱ(145. 7±70. 3 ml/min, P<0. 05). There was on significant differ- ence between the free flow after dilatation of the left and right ITA in the group Ⅰ (left 199. 3±69. 6 ml/mm, right 198. 9±61. 8 ml/mm, respectively). It was concluded that preparation of the ITA with the skeletonization technique resulted in significantly higher free flow capacity than in pedicled grafts and would improve the results of arterial revascularization. The complication rate seems to be lower than with the conventional method.展开更多

文摘This is a review of the first 10 coronary artery bypass surgeries performed by the local team. The mean age was 62 years old [45 - 74]. The patients were predominantly male, with a M/F ratio of 4:1. Cardiovascular risk factors were mainly myocardial infarction (MI) (60%), hypertension (50%), obesity (40%) and diabetes (30%), with at least two risk factors per patient. Angina was the main symptom (80%). The average time from presentation to surgery was 8 months. The mean Euroscore 2 was 2.92 ± 1.65 [1.33 - 6.60]. Coronary angiography revealed an average of 2 lesions per patient, with 3-vessel involvement in 70% of cases: the Interventricular artery (IVA) (100%), the right coronary artery (90%) and the circumflex artery (70%). On echocardiography, the mean Left ventricular ejection fraction (LVEF) was 59% [33% - 76%]. All patients underwent median sternotomy with bypass grafting. The average duration of the cardiopulmonary bypass was 150 min [46 - 275 min];that of aortic clamping, 120 min [43 - 232 min]. The grafts used were internal thoracic artery (ITA) in 100% of cases (80% on the left and 20% on the right), and the great saphenous vein (GSV) in 60% of cases (50% on the left and 10 on the right). Double bypass was performed in 60% of cases, single bypass in 30% and triple bypass in 10%. The bypasses were performed on the IVA (100%), the middle lateral of the circumflex (30%) and the bisector (20%). The average time to extubation was 11 hours and the length of stay in the intensive care unit was 7 days [03 - 17 days]. One patient had a reoperation on Day 0 post-op. The average hospital stay was 13 days [06 - 27 days]. Complications occurred in nine of the patients (90%), with a predominance of infectious and neurological complications. Overall operative mortality was 3%, all in intensive care.
文摘Background: Serum albumin, a vital plasma protein, helps maintain intravascular colloidal osmotic pressure, cardiac output, and renal function. Low preoperative serum albumin is linked to poor outcomes, including acute kidney injury (AKI), after off-pump coronary artery bypass (OPCAB) surgery. This study aimed to assess the relationship between preoperative serum albumin levels and early postoperative renal injury. Methods: This prospective comparative cross-sectional study was conducted from August 2019 to February 2021 at the National Heart Foundation Hospital & Research Institute, Bangladesh. It included 160 adult patients with normal preoperative renal function undergoing OPCAB. Patients were divided into two groups: Group A (serum albumin ≥ 4.0 gm/dl) and Group B (serum albumin Results: Preoperative serum albumin was significantly different between groups (Group A: 4.21 ± 0.05 gm/dl, Group B: 3.69 ± 0.04 gm/dl, p = 0.028). Group B had a higher incidence of hypertension (71.25% vs. 51.25%, p st and 3rd postoperative days were higher in Group B (p th day. Postoperative AKI occurred in 18.75% of Group A and 36.25% of Group B. Multivariate regression indicated that low preoperative serum albumin is an independent risk factor for postoperative AKI (p = 0.012, OR = 1.815, CI: 0.675 - 1.162). Conclusion: Preoperative serum albumin level is a valuable predictor of postoperative renal function. Ensuring high normal serum albumin levels before surgery can help minimize the risk of postoperative AKI.
文摘Coronary heart disease is among the most prevalent and costly of all global health problems. Coronary artery bypass grafting (CABG) has been increasingly used since the 1960s. Coronary heart disease is a leading cause of death worldwide, including Sudan. Self-efficacy and functional capacity is a critical factor for quality of life in patients who has undergone CABG as well as for their caregivers from their families. Aim of the Study: To explore the effects of an educational program on self-efficacy and functional capacity of patients after CABG. 1) There will be no significant difference between the intervention group and control group concerning knowledge regarding Self-efficacy and functional capacity post CABG surgery. 2) The application of our educational program for the patients will enhance the patients with CABG surgery and improve knowledge about Self-efficacy and functional capacity post CABG surgery. 3) There are some socio demographic factors that affect the response to the educational program. Methods: This was a quasi-experimental, interventional and hospital-based study, including pre-test, a post-test and follow-up test, with a control group, conducted during the period from September 2014 to June 2019. Patients were recruited consecutively to the cases and control group using convenience sampling. The sample consisted of 76 patients;41 as cases and 35 as control group. The sample included those who had undergone CABG in Khartoum State. Relevant data were collected using a checklist to monitor the effect of a health education program on self-efficacy and functional capacity of the patients. Result: The results showed marked improvement in patients’ self-efficacy and functional capacity between pretest and posttest for the study group;p-value = (0.001) in the health status of cases in comparison to the control group. The indices were observed to be higher for patients who received a nursing educational program throughout the study period;p-value = (0.002).

文摘BACKGROUND Acute kidney injury(AKI)after coronary artery bypass graft(CABG)surgery is associated with significant morbidity and mortality.This retrospective study aimed to establish a risk score for postoperative AKI in a Chinese population.METHODS A total of 1138 patients undergoing CABG were collected from September 2018 to May 2020 and divided into a derivation and validation cohort.AKI was defined according to the Kidney Disease Improving Global Outcomes(KDIGO)criteria.Multivariable logistic regression analysis was used to determine the independent predictors of AKI,and the predictive ability of the model was determined using a receiver operating characteristic(ROC)curve.RESULTS The incidence of cardiac surgery–associated acute kidney injury(CSA-AKI)was 24.17%,and 0.53%of AKI patients required dialysis(AKI-D).Among the derivation cohort,multivariable logistic regression showed that age≥70 years,body mass index(BMI)≥25 kg/m2,estimated glomerular filtration rate(eGFR)≤60 mL/min per 1.73 m2,ejection fraction(EF)≤45%,use of statins,red blood cell transfusion,use of adrenaline,intra-aortic balloon pump(IABP)implantation,postoperative low cardiac output syndrome(LCOS)and reoperation for bleeding were independent predictors.The predictive model was scored from 0 to32 points with three risk categories.The AKI frequencies were as follows:0-8 points(15.9%),9-17 points(36.5%)and≥18 points(90.4%).The area under of the ROC curve was 0.730(95%CI:0.691-0.768)in the derivation cohort.The predictive index had good discrimination in the validation cohort,with an area under the curve of 0.735(95%CI:0.655-0.815).The model was well calibrated according to the Hosmer-Lemeshow test(P=0.372).CONCLUSION The performance of the prediction model was valid and accurate in predicting KDIGO-AKI after CABG surgery in Chinese patients,and could improve the early prognosis and clinical interventions.
文摘Several studies have shown that coronary artery bypass graft surgery （CABG） is superior to percutaneous coronary intervention （PCI） in patients with diabetes and multi-vessel disease. Whether this advantage of CABG over PCI is confined to diabetics who require insulin is unknown. We review the published literature comparing CABG with PCI in diabetics including 8 cohorts and 4,786 patients. There was a lower rate for all-cause mortality （Relative risk （RR）： 0.78, 95% confidence interval （CI）： 0.62-0.99）, and for major adverse cardiac and cerebrovascular events （MACCE, RR： 0.59, 95% CI： 0.47-0.75） for CABG compared to PCI. Composite outcome of mortality, myocardial infarction and stoke was similar between CABG and PCI （RR： 0.87, 95% CI： 0.54-1.42）. Visual inspection of the forest plots showed that in most analyses, the point estimates of the RR are similar between the insulin requiring group and non-insulin requiring group. On meta-regression, there was no interaction between status of insulin requirement and revascularization strategies （P 〉 0.05 for all）. The pre- sented data on the still unpublished analysis of the FREEDOM trial showed similar results. Thus, in the current era, CABG is superior to PCI with lower mortality and MACCE rates, but the state of insulin requirement had no effect on the outcomes from the two revascularization strategies.
文摘Background: Insufficient capacity for cardiac surgery results in extensive waiting time for patients requiring coronary artery bypass grafting (CABG). Previous studies have reported a consequence of an increased risk of mortality while waiting for CABG. Identification of risk factors for mortality is important in patients waiting for CABG. Objectives: To assess mortality rates and identify risk factors for mortality of patients waiting for CABG. Methods: This retrospective cohort study was done on patients waiting for elective CABG in dr. Kariadi General Hospital from January 2018 to December 2020. Identification of risk factors associated with mortality was done on patients who were waiting for CABG using logistic regression methods. Results: There were 162 patients fulfilling the criteria, with a mean waiting time for surgery of 9.8 months. While waiting for CABG surgery, 32 (19.7%) patients died of any cause. Independent risk factors for death while waiting for CABG included left ventricular ejection fraction ≤ 45% (OR 4.75;95% CI 1.76 - 12.78;p = 0.002), left main disease (OR 4.12;95% CI 1.50 - 11.27;p = 0.006), serum creatinine ≥ 1.5 mg/dl (OR 3.71;95% CI 1.41 - 9.74;p = 0.008), and a number of coronary artery disease risk factors ≥ 3 (OR 3.34;95% CI 1.24 - 8.99;p = 0.017). Conclusions: Long waiting time for CABG is associated with a high mortality rate which is influenced by left ventricular ejection fraction ≤ 45%, left main disease, serum creatinine ≥ 1.5 mg/dl, and a number of coronary arteries disease risk factors ≥ 3.
文摘Introduction: In this study we examined the early results of coronary artery bypass surgery in our female patients and compared them with those of our male patients. Material and Methods: One thousand and ninety four patients who underwent coronary artery bypass surgery between January 2009 and December 2011 inour clinic were included into this study. Three hundred and thirteen female patients (group 1) were compared to 781 male patients (group 2). Results: The mean age of group 1 was 61.4 ± 9.6, and the mean age of group 2 was 58.1 ± 9.6 (p < 0.001). The ratio of diabetes mellitus and hypertension in group 1 was higher than that of group 2 (p < 0.001). There were no significant difference between two groups when compared regarding the need for inotropics after weaning from cardiopulmonary bypass, cross clamp and total cardiopulmonary bypass periods (p > 0.05). It was found that the amount of drainage was higher in group 1 than group 2 (p < 0.001). There was no significant difference between two groups when compared in terms of mortality, re-operation (because of bleeding), postoperative atrial fibrillation, need for intraaortic balloon pump, usage of levosimendan, cerebrovascular accident, chronic renal failure, discharging intervals and period in intensive care unit. It was found that sternal wound infection was higher in group 1 than group 2 (p < 0.05). Conclusion: We consider that female gender does not put an additional risk to increase mortality and morbidity in coronary artery bypass surgery.

文摘Objectives To test the feasibility of the use of high thoracic epidural anesthesia as a sole anesthetic in patients undergoing off pump coronary artery bypass surgery, avoiding general anesthesia. Methods Between October 2002 to April 2003, twenty five cases underwent beating heart coronary artery revascularization without endotracheal general anesthesia, using high thoracic epidural anesthesia and analgesia. All the patients underwent epidural catheterization on the evening before the surgery. Resuits The patients in all received 71 grafts (single n = 11, double n = 5, triple n = 6, quadruple n = 3). Six patients underwent repeat coronary artery bypass. Except one was converted to general anesthesia and cardiopulmonary bypass, the other patients underwent off-pump coronary artery bypass graft surgery, 2 patients underwent grafting via left thoracotomy (MIDCAB) and the rest through mid sternotomy. There was no mortality. Mean length of stay in the intensive care unit was 16 .2 ( 4.2 hours and hospital was 3.0(1.2 days. Conclusions Our experience confirms the feasibility of performing multiple coronary artery bypasses in conscious patients without endotracheal general anesthesia
文摘Objective The rate of post-operative complications has been increased with the changes in patients’age,prolonged duration,more severe and diffused lesions,and more patients with complications in recent years. We try to identify the risk factors associated with prolonged stay in the intensive care unit (ICU) after coronary artery bypass graft surgery (CABG) . Methods 1623 patients who received CABG surgery in Beijing Anzhen Hospital
文摘To investigate the effects of patient-controlled intravenous analgesia (PCIA) with lornoxicam and fentanyl on arrhythmia and the expression of platelet membrane glycoproteins in patients with coronary artery disease (CAD) after abdominal surgery.Methods Eighty ASA Ⅱ or Ⅲ patients with CAD aged 51～66 yrs weighing 59～68 kg presenting for abdominal surgery participated in this study.CAD was diagnosed by clinical symptoms and ischemic changes on ECG.The patients were premedicated with intramuscular henobarbital 0.1 g and scopolamine 0.3 mg.Anesthesia was induced with fentanyl,droperidol,propofol and vecuronium and maintained with propofol,fentanyl and vecuronium.The patients received PCIA after operation.The PCIA solution contained fentanyl 0.9 mg and droperidol 5 mg in 100 ml of normal saline (N.S.) in group A (n=40) or lornoxicam 56 mg,fentanyl 0.2 mg and droperidol 5 mg in 100 ml N.S. in group B (n=40).In group A the loading dose was fentanyl 0.05 mg and group B lornoxicam 4 mg.PCIA included a background infusion at 2 ml·h -1 and a bolus of 0.5 ml with a 15 min lock-out.VAS(0=no pain,10= worst pain) was used to measure pain intensity.In addition to BP,HR and SpO2 monitoring ECG was continuously monitored with a Holter monitor after operation.Blood samples were taken from peripheral vein before and 6 h after operation and on the 1st,2nd,7th and 8th postoperative days for determination of the expression of CD 62p ,CD 63 and CD 41 /CD 61 on the platelet membrane,platelet count,prothrombin time (PT) thrombin time (TT) and partial thromboplastin time (PTT).Results The two groups were comparable with respect to sex,age,body weight,severity of CAD,duration of operation and intraoperative blood loss.The patients received no blood transfusion during operation.There was no significant difference in VAS score,platelet count,PT,TT and PTT between the two groups.The incidence of atrial and ventricular premature beat on ECG and the expression of CD 41 /CD 61 ,CD 62p and CD 63 on the platelet membrane were significantly lower in group B than in group A on the 7th and 8th postoperative days(P<0.05 or 0.01).Conclusion Postoperative PCIA with lornoxicam and fentanyl can more effectively reduce the incidence of postoperative arrhythmia in patients with CAD.Suppression of activation of platelets by lornoxicam may contribute to the mechanism.10 refs,3 tabs.

文摘The association between atrial fibrillation（AF） after coronary artery bypass grafting（CABG） and the surgical techniques selected has been extensively reported. However, no consistent results were obtained. In the present study, a meta-analysis was conducted by searching the electronic databases Pub Med, Embase, Web of Science, and Cochrane to identify the association of post-CABG AF with on-pump（conventional CABG, c CABG） or off-pump CABG（OPCABG）. Outcomes from randomized clinical trials（RCTs） and propensity score matching（PSM） trials were pooled by using the fixed-effect or the random-effect modeling method, and verified by the quality-effect modeling method. There were 35 studies with 36 independent reports that met the inclusion criteria and were eventually included in our meta-analysis. The total odds ratio（OR） of the incidence of post-CABG AF between OPCABG and c CABG was 0.80（95% CI 0.71–0.91）. The 25 randomized clinical trials（RCTs） had an OR of 0.69（95% CI 0.56–0.86）, while the OR of the 11 PSM trials was 0.88（95% CI 0.77–1.00）. Twenty-six studies involving the patients at a mean age no more than 65 years showed an OR of 0.76（95% CI 0.64–0.90）, whereas 10 studies with patients greater than 65 years old showed an OR of 0.90（95% CI 0.78–1.05）. The results of this meta-analysis suggest that OPCAB surgery may reduce the incidence of post-CABG AF when compared to c CABG and that younger patients may benefit more from OPCAB and have a lower incidence of post-CABG AF.
文摘Objective: Hemodynamic deterioration during positioning of the heart has been the most critical complication of off-pump coronary artery bypass surgery. Pre-operative use of intra-aortic balloon pump has been shown to prevent this complication in high risk patients. The role of balloon pump in high risk patients has been questioned by our group. We modified the role of balloon pump in our patients, thus avoiding the conversion to cardiopulmonary bypass. Methods: 4063 off-pump coronary bypass surgeries were performed by a single surgeon in our center, over thirteen years. 130 intra-aortic balloons used between July 2002 and December 2015 were removed from the the-ater, once the distal anastomosis was performed. We studied this group of patients for—time and need for insertion, duration of balloon used, local insertion problems and survival. Results: Initially, we inserted intra-aortic balloons in high risk patients. We observed that, patients with low ejection fraction and patients with critical left main coronary artery disease were not the ones who actually needed balloon pump support. It was the patients who had ongoing ischemia, with preserved left ventricular function, and ST depression intra-operatively, who needed balloon pump support to perform complete anatomical revascularization. Conclusions: Intra-aortic balloon pump has helped us to position the heart without hemodynamic instability, thereby avoiding conversion to cardio-pulmonary bypass. This enabled us to perform off-pump surgery in virtually all areas of the heart, thus maintaining perfect hemodynamics.
文摘A single coronary artery is a very rare condition,commonly associated with other congenital anomalies.It could be generally considered as neither benign nor malignant form of congenital coronary artery anomalies since its pathophysiological and clinical implications grossly depend on different anatomical patterns defined by the site of origin and distribution of the branches.By presenting the patient who underwent successful coronary artery bypass grafting and aortic valve replacement surgery in a presence of isolated single coronary artery,we intend to emphasize natural and procedural risks and distinguish casual from causal in this extremely rare clinical and surgical scenario.
文摘BACKGROUND Pregnancy-associated spontaneous coronary artery dissection(PSCAD)is an important cause of chest pain and acute myocardial infarction in pregnant and postpartum women.Pregnancy is considered an isolated risk factor for spontaneous coronary artery dissection.The etiology,pathogenesis,and incidence of PSCAD are not known.CASE SUMMARY We present a case of a 33-year-old postpartum female who presented with sudden onset chest pain and was diagnosed with spontaneous coronary artery dissection and needed urgent catheterization revealing left anterior descending coronary artery dissection.She underwent emergent coronary artery bypass graft surgery with good post-operative recovery.CONCLUSION Most patients with PSCAD can be managed conservatively with medical management and have good outcomes.Patients with high-risk presentations benefit from the invasive approach.Coronary artery bypass graft may be required in select few patients based on angiography findings.Due to the risk of recurrent spontaneous coronary artery dissection,subsequent pregnancies are discouraged.
文摘Background Cardiopulmonary bypass (CPB) produces a well documented diffuse inflammatory response that affects multiple organ systems. To avoid the deleterious effects of cardiopulmonary bypass, off pump coronary artery bypass grafting is becoming increasingly popular world wide. We reviewed our experience of complete coronary artery revascularization on the beating heart without CPB. Methods From Aug 1998 to Aug 2000, 860 off pump revascularizations (99%since January 1999) were performed at Manipal Hospital Heart Foundation. The patients consist of males 757(88%), females 103(12%). Averaged age 64.2±15 years. All surgeries were performed through a median sternotomy. Exposure techniques are tailored to individual vessels and cardiac regions. Local immobilization is performed with octopus. Vascular control is achieved with occluders and shunts. Results Among 860 off pump CABG patients. Single graft 72 (8.3%), two grafts 208 (24.2%), three grafts 469 (54.5%), four grafts 101 (11.8%), five graft 10 (1.2%). The average number of grafts per patient was 2.72±0.32. Operative mortality was 0.69%(6 patients). Anesthetic time 3.9±1.2hours, extubation time 6±2.5 hours, Blood requirement 360±90 ml, Preoperative LVEF 60.2±8.5%, Post LVEF 64.1±14%Low cardiac output 48 patients (5.6%), IABP requirement: 25 patients(2.9%), 25 patients converted to CPB during OP CAB(2.9%)and 20 of them were done with on pump beating heart. 25 patients showed myocardial ischemic and 16 patients showed perioperative myocardial infarction. ICU stay 1.1±0.8 days, hospital stay 6.2±1.1 days. Conclusion Off-pump coronary artery bypass in complete revascularization is a safe, effective technique and suitable.
文摘The free flow of skeletonized ITA grafts was compared with that of pedicled ITA grafts. One hundred patients with coronary artery diseases underwent elective CABG. In the group Ⅰ(n= 50), the left ITA was dissected using the skeletonization technique. In the group Ⅱ(n=50), the ITA was harvested as a pedicled graft. Free flow of the ITA was recorded before and 15 min after in- traluminal application of diluted papaverine. Mean arterial pressure was maintained at 9. 31 kPa (70 mmHg). The results showed that before the application of papaverine, free flow of skeletonized and pedicled ITA grafts was identical between the two groups. After treatment with papaverine, the maximum free flow was significantly higher in the skeletonized ITA's in the group Ⅰ(199. 3±69. 6 ml/min) than in the group Ⅱ(145. 7±70. 3 ml/min, P<0. 05). There was on significant differ- ence between the free flow after dilatation of the left and right ITA in the group Ⅰ (left 199. 3±69. 6 ml/mm, right 198. 9±61. 8 ml/mm, respectively). It was concluded that preparation of the ITA with the skeletonization technique resulted in significantly higher free flow capacity than in pedicled grafts and would improve the results of arterial revascularization. The complication rate seems to be lower than with the conventional method.
